Additional data are presented on the maintenance of kappa particles in cells of P. aurelia (stock 51) after removal of the gene K. It is shown that kappa particles may be maintained for as long as twenty-seven fissions in the absence of K, or may disappear before eight fissions. Slight retardation in fission rate of paramecia quickly eliminates kappa particles. The bearing of these results on the metagon theory is discussed.
